LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 403,695, dated May 21, 1889.

i I Application filed October 18, 1887. Serial No. 252,666. (No model.)

To fill whom it may concern:

Be it known that I, .1 Aims POWELL, a citizen of the United States, residing at Cincinnati, in the countyof ll'amilton, State of Ohio, have invented certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings.

The first part of my present improvements comprises a novel combination of standard, oil-reservoir, supporting-arms, channels, and ascending sight-feed tube, whereby a cheap and reliable lubricator is produced, the details of these devices being hereinafter more fully described.

The second part of my improvements comprises a specific combination of devices for forming a trap in the channel or tube that conducts water from an elevated condenser through a lateral arm to the oil-reservoir of a lubricator, the object of this trap being to prevent oil ascending said channel, tube, or passage, as hereinafter more fully described.

In the annexed drawings, Figure l is asectionized elevation of my improved lubricator, the nipple-valve being closed. Fig. 2 is an enlarged horizontal section of the lower arms of the standard, said section being taken at the line 5 5 of Fig. 1. Fig. 3 is an enlarged axial section of the discharge-nipple and its accessories. Fig. i is an enlarged vertical section of a modification of the trap.

A represents the base-connection of the lubricatonsai d base being provided with a screwthreaded shank, a, an axial channel, a, and a haml-wheel,A, that controls a valve or regulating-cock.

Attached to this base-connection at a" is the tubular standard B, having at bot-tom a pair of lateral arms, C D, and at top a single lateral arm, E, said arms 0 D E being preferably integral with said standard and the arm E being vertically above the arm C. Furthermore, this standard has a main channel, F, and a secondary channel, G, the lower end of channel F communicating with the base-channel a, while its upper end takes the shape of an inclined duct, f, leading into the sight-tube, this duct f being arranged longitudinally of the upper arm, E. f is an upward branch of this duct, which branch communicates with a steam-pipe, H, leading up almost to the top of j, beneath it. j

the neck t of condenser I, said neck being closed by a screw-threaded cap, i. Condenser I is coupled to the tubular standard at I). The upper arm, E, is bored vertically to admit the glass cylinder or sight-feed tube J and is threaded to permit the engagement of a screwplug, K. This plug retains the sight-tube in place, andis pierced with one or more lateral ports, It", that allow a free communication between said tube and the duct f,

The lower end of tube or cylinder J rests within a socket, c, of arm 0, as more clearly represented in Fig. 3, and has a packing-ring, is a similar ring interposed between the tube J and plug K. Ring-j rests upon the head L of the oildischarge nipple I, said head being screwed into the socket r, and being furnished with a seat, I, for a valve,M, that regulates the ascent of oil through said nipple. m is the stem or handle of said regulator.

Situated beneath thehead L is an enlarged oil-receiving chamber, N, having a feed-duct, 02, leading into the upper part of reservoir 0, which depends from the arm D, and is preterably integral therewith, said reservoir being provided with a filling-plug, o, and draincock 0'. Feed-duct amay be made by means of a core, or it can be drilled through the arms (I I) and its outer end be closed with a screw, 01, as seen in Fig. 2.

The secondary channel G of standard 1 is carried down almost to the under side of arm D, and then runs up toward the top of reservoir O, as at G, thus forming a bend or trap, g, which is constantly filled with condensed water.

P is a barrier or ledge beneath the lower end of steam-pipe l'I.

Rand R are the stulling-box glands for the sight-feed tube J.

The operation of this lubricator is as follows: The apparatus is first attached to a pipe or steam-chest in the usual manner and the reservoir 0 is charged with oil, after which act cap L" is slightly unscrewed and the valve or cock in the base-connection is opened for the purpose of expelling air from the lubricator and then said cap is tightened. \Vhen steam is thus admitted, suflicicut condensation takes place to (ill. the vessel I, while the water running down within the pipe l-l into the duct f and thence through the ports 70 of plug K insures the rapid filling of sight-tube J with clear water. The water from the'condenser flows down the secondary channel G of standard B, and thus obtains access to the from the reservoir, flows along the horizontal duct n into the receiving-chamber N, Where it collects in a considerable quantity, and finally escapes through the nipple Z and sighttube J into the duct f. The oil then flows along this duct, and is discharged over the upper or elevated end of the same directly into the main channel F of standard B and descends the channel a on its way to the engine. During this operation of the lubricator the ledge or shelf P serves as a barrier that prevents the falling water from pipe H dropping directly into the main channel F, the water being thus deflected or shed into the inclined duct f, so as to insure a constant filling of the sight-tube J.

From the above description it is apparent that a considerable pressure is exerted again st the oil in the reservoir; but this pressure can never force the lubricant up the channel G and thence into the condenser I, because the shown as being provided with a single chan- 'nel, F, the secondary channel G being omitted.

this counterbore, in order that the Water from the condenser may ascend the inclined channel T and thus obtain access to the reservoir. It will be noticed that the delivery end of this channel T is considerably higher than its receiving end, by which arrangement a watertrap is formed that prevents oil backing up into the condenser. This illustration shows a horizontal duet, f for conducting Water" to the sight-feed chamber or tube, the advantage of an inclined duct being obtained by a curb or dam, U, that insures the complete filling of said duct before the water can flow over said dam and run down the channel F.

I claim as my invention 1. A lubricator having a supporting-standard provided at bottom with a pair of lateral arms and at top with a condenser and a single lateral arm traversed by a duct communicating with the sight-feed chamber, steampipe, and main channel in the manner described, while the lever-arms are traversed by a channel extending from the top of reservoir to the bottom of said chamber, said reservoir being pendent from the arm, and being supplied With Water by a channel or pipe lead ing up to the condenser, all of said parts being combined to operate substantially as set forth.

2. The combination, in a lubricator, of a channeled and counterbored standard, B F S,

steam-pipe I-I, elevated condenser I, oil-reservoir O, and lateral arm D, which arm connects said reservoir 0 with the upper part of said standard B F S, and has an inclined channel, 1, connecting the upper portion of said reservoir with the lower part of said counterbore S, all as herein described, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
